The current means of feeding text to the Arduino hasn't been well
thought out, but basically you can send (lightly encoded) strings to
its 'screen memory', and have it transmit the screen when ready
(and all within the 2kB SRAM of the Uno)

Pardon the PETSCII. I didn't have a ASCII-indexed font bitmap
immediately available, and was too in the zone to go looking...
